3 The recommended way of installing Icinga 2 is to use packages. The Icinga
4 project provides both release and development packages for a number
7 Please check the documentation in the [doc/](doc/) directory for a current list
8 of available packages and detailed installation instructions.
10 There are a number of known caveats when installing from source such as
11 incorrect directory and file permissions. So even if you're planning to
12 not use the official packages it is advisable to build your own Debian
17 The following requirements need to be fulfilled in order to build the
18 application using a dist tarball (package names for RHEL and Debian in
23 * C++ compiler (gcc-c++ on RHEL, build-essential on Debian)
24 * OpenSSL library and header files (openssl-devel on RHEL, libssl-dev on Debian)
25 * Boost library and header files (boost-devel on RHEL, libboost-all-dev on Debian)
27 * GNU flex (flex) >= 2.5.35
28 * recommended: libexecinfo on FreeBSD (automatically used when Icinga 2 is
29 installed via port or package)
30 * recommended: GNU readline (readline-devel on RHEL, libreadline-dev on Debian)
31 * recommended: ncurses (ncurses-devel on RHEL, libncurses-dev on Debian)
32 * optional: MySQL (mysql-devel on RHEL, libmysqlclient-dev on Debian); set CMake
33 variable `ICINGA2_WITH_MYSQL` to disable this module
34 * optional: PostgreSQL (postgresql-devel on RHEL, libpq-dev on Debian); set CMake
35 variable `ICINGA2_WITH_PGSQL` to disable this module
36 * optional: YAJL (yajl-devel on RHEL, libyajl-dev on Debian)
38 Note: RHEL5 ships an ancient flex version. Updated packages are available for
39 example from the repoforge buildtools repository.
41 * x86: http://mirror.hs-esslingen.de/repoforge/redhat/el5/en/i386/buildtools/
42 * x86\_64: http://mirror.hs-esslingen.de/repoforge/redhat/el5/en/x86_64/buildtools/
46 By default Icinga will run as user 'icinga' and group 'icinga'. Additionally the
47 external command pipe and livestatus features require a dedicated command group
48 'icingacmd'. You can choose your own user/group names and pass them to CMake
49 using the `ICINGA2_USER`, `ICINGA2_GROUP` and `ICINGA2_COMMAND_GROUP` variables.
53 # useradd -c "icinga" -s /sbin/nologin -G icingacmd -g icinga icinga
55 Add the web server user to the icingacmd group in order to grant it write
56 permissions to the external command pipe and livestatus socket:
58 # usermod -a -G icingacmd www-data
60 Make sure to replace "www-data" with the name of the user your web server
64 ## Building Release Tarballs
66 In order to build a release tarball you should first check out the Git repository
67 in a new directory. If you're using an existing check-out you should make sure
68 that there are no local modifications:
74 Here's a short check-list for releases:
76 Update the [.mailmap](.mailmap) and [AUTHORS](AUTHORS) files
78 $ git log --use-mailmap | grep ^Author: | cut -f2- -d' ' | sort | uniq > AUTHORS
80 Bump the version in icinga2.spec.
81 Update the [ChangeLog](ChangeLog), [doc/1-about.md](doc/1-about.md) and [INSTALL.md](INSTALL.md)
83 Commit these changes to the "master" branch.
85 $ git commit -v -a -m "Release version <VERSION>"
87 Create a signed tag (tags/v<VERSION>).
91 $ git tag -u EE8E0720 -m "Version <VERSION>" v<VERSION>
94 $ git tag -u D14A1F16 -m "Version <VERSION>" v<VERSION>
100 Merge the "master" branch into the "support/2.2" branch (using --ff-only).
102 $ git checkout support/2.2
103 $ git merge --ff-only master
104 $ git push origin support/2.2
106 Note: CMake determines the Icinga 2 version number using `git describe` if the
107 source directory is contained in a Git repository. Otherwise the version number
108 is extracted from the [icinga2.spec](icinga2.spec) file. This behavior can be overridden by
109 creating a file called `icinga-version.h.force` in the source directory.
110 Alternatively the `-DICINGA2_GIT_VERSION_INFO=ON option` for CMake can be used to
111 disable the usage of `git describe`.
115 Use `git archive` to build the release tarball:
118 $ git archive --format=tar --prefix=icinga2-$VERSION/ tags/v$VERSION | gzip >icinga2-$VERSION.tar.gz
120 Finally you should verify that the tarball only contains the files it should contain:
123 $ tar ztf icinga2-$VERSION.tar.gz | less
128 Once you have installed all the necessary build requirements you can build
129 Icinga 2 using the following commands:
131 $ mkdir build && cd build
136 You can specify an alternative installation prefix using `-DCMAKE_INSTALL_PREFIX`:
138 $ cmake .. -DCMAKE_INSTALL_PREFIX=/tmp/icinga2
140 In addition to `CMAKE_INSTALL_PREFIX` the following Icinga-specific cmake
141 variables are supported:
143 - `ICINGA2_USER`: The user Icinga 2 should run as; defaults to `icinga`
144 - `ICINGA2_GROUP`: The group Icinga 2 should run as; defaults to `icinga`
145 - `ICINGA2_GIT_VERSION_INFO`: Whether to use Git to determine the version number; defaults to `ON`
146 - `ICINGA2_COMMAND_GROUP`: The command group Icinga 2 should use; defaults to `icingacmd`
147 - `ICINGA2_UNITY_BUILD`: Whether to perform a unity build; defaults to `OFF`
148 - `ICINGA2_PLUGINDIR`: The path for the Monitoring Plugins project binaries; defaults to `/usr/lib/nagios/plugins`
149 - `ICINGA2_RUNDIR`: The location of the "run" directory; defaults to `CMAKE_INSTALL_LOCALSTATEDIR/run`
150 - `CMAKE_INSTALL_SYSCONFDIR`: The configuration directory; defaults to `CMAKE_INSTALL_PREFIX/etc`
151 - `ICINGA2_SYSCONFIGFILE`: Where to put the config file the initscript/systemd pulls it's dirs from;
152 defaults to `CMAKE_INSTALL_PREFIX/etc/sysconfig/icinga2`
153 - `CMAKE_INSTALL_LOCALSTATEDIR`: The state directory; defaults to `CMAKE_INSTALL_PREFIX/var`
154 - `USE_SYSTEMD=ON|OFF`: Use systemd or a classic SysV initscript; defaults to `OFF`
155 - `INSTALL_SYSTEMD_SERVICE_AND_INITSCRIPT=ON|OFF` Force install both the systemd service definition file
156 and the SysV initscript in parallel, regardless of how `USE_SYSTEMD` is set.
157 Only use this for special packaging purposes and if you know what you are doing.
159 - `ICINGA2_WITH_MYSQL`: Determines whether the MySQL IDO module is built; defaults to `ON`
160 - `ICINGA2_WITH_PGSQL`: Determines whether the PostgreSQL IDO module is built; defaults to `ON`
161 - `ICINGA2_WITH_CHECKER`: Determines whether the checker module is built; defaults to `ON`
162 - `ICINGA2_WITH_COMPAT`: Determines whether the compat module is built; defaults to `ON`
163 - `ICINGA2_WITH_DEMO`: Determines whether the demo module is built; defaults to `OFF`
164 - `ICINGA2_WITH_HELLO`: Determines whether the hello module is built; defaults to `OFF`
165 - `ICINGA2_WITH_LIVESTATUS`: Determines whether the Livestatus module is built; defaults to `ON`
166 - `ICINGA2_WITH_NOTIFICATION`: Determines whether the notification module is built; defaults to `ON`
167 - `ICINGA2_WITH_PERFDATA`: Determines whether the perfdata module is built; defaults to `ON`
169 ### Building Icinga 2 RPMs
171 Setup your build environment on RHEL/SUSE and copy the generated tarball from your git
172 repository to `rpmbuild/SOURCES`.
173 Copy the icinga2.spec file to `rpmbuild/SPEC` and then invoke
175 $ rpmbuild -ba SPEC/icinga2.spec
177 ### Building Icinga 2 Debs
179 Setup your build environment on Debian/Ubuntu and run the following command straight from
180 the git repository checkout:
182 $ ./debian/updateversion && dpkg-buildpackage -uc -us
186 Icinga 2 comes with a single binary that takes care of loading all the relevant
187 components (e.g. for check execution, notifications, etc.):
189 # /usr/sbin/icinga2 daemon
190 [2014-12-18 10:20:49 +0100] information/cli: Icinga application loader (version: v2.2.2)
191 [2014-12-18 10:20:49 +0100] information/cli: Loading application type: icinga/IcingaApplication
192 [2014-12-18 10:20:49 +0100] information/Utility: Loading library 'libicinga.so'
193 [2014-12-18 10:20:49 +0100] information/ConfigCompiler: Compiling config file: /home/gbeutner/i2/etc/icinga2/icinga2.conf
194 [2014-12-18 10:20:49 +0100] information/ConfigCompiler: Compiling config file: /home/gbeutner/i2/etc/icinga2/constants.conf
197 Icinga 2 can be started as daemon using the provided init script:
199 # /etc/init.d/icinga2
200 Usage: /etc/init.d/icinga2 {start|stop|restart|reload|checkconfig|status}
202 Or if your distribution uses systemd:
204 # systemctl {start|stop|reload|status|enable|disable} icinga2.service
206 Icinga 2 reads a single configuration file which is used to specify all
207 configuration settings (global settings, hosts, services, etc.). The
208 configuration format is explained in detail in the [doc/](doc/) directory.
210 By default `make install` installs example configuration files in
211 `/usr/local/etc/icinga2` unless you have specified a different prefix or
